Abstract: An example system for molding a photocurable material into a planar object includes a first mold structure having a first mold surface, a second mold structure having a second mold surface, and one or more protrusions disposed along at least one of the first mold surface or the second mold surface. During operation, the system is configured to position the first and second mold structures such that the first and second mold surfaces face each other with the one or more protrusions contacting the opposite mold surface, and a volume having a total thickness variation (TTV) of 500 nm or less is defined between the first and second mold surfaces. The system is further configured to receive the photocurable material in the volume, and direct radiation at the one or more wavelengths into the volume.

Abstract: Polylactide (PLA) parts can be crystallized via two procedures. In the first procedure, i.e. a 2-step post-mold annealing process, the complete crystallization of PLA parts can be done after molding in a secondary operation called as post-mold annealing to make higher heat-resistant PLA parts. There are limitations to this 2-step operation, namely, a) warpage of parts with complex geometries, and b) scaling up higher production volume times. In the second procedure, i.e. 1-step in-mold annealing process, the complete crystallization of PLA parts can be done in the mold itself by holding the temperature of the mold at the crystallization temperature of PLA which is about 100° C. The 1-step in-mold annealing process using a masterbatch blended with neat PLA results in a highly crystalline article produced in a significantly lower cycle time.

Abstract: The present disclosure relates to a process for dyeing a hydrolysis-resistant polyester film. The process comprises dyeing of a hydrolysis resistant polyester film in a dye bath comprising at least one coloring agent (dye), at least one polyhydric alcohol, and optionally at least one UV absorber to obtain a dyed film. The dyed film is subjected to quenching followed by cleaning and drying to obtain a dyed hydrolysis-resistant polyester film. The process of the present disclosure is simple, economical, improve hydrolysis resistance, and also retains the mechanical properties of the film when exposed to harsh environmental conditions.

Abstract: A method for additive manufacturing using releasable inks on a substrate mold includes applying a surface treatment to a surface of a mold defining an article for manufacturing, and depositing an ink including particles or fibers of a trace material onto the surface treatment. The particles are coated with a functionalization agent based on a surface energy of the surface treatment for providing a release on demand of the printed trace. The deposited ink is cured to evaporate a solvent carrier, and sintered to bond or melt the particles or fiber together r. The article is molded by adding a molding substance to the mold over the trace, and releasing the molded article from the mold, such that the trace adheres to either the mold or the article based on the functionalization agent providing the trace greater adhesion to the mold or the article to effect the release on demand.
